SAMUEL L. ALLEN, OF OINNAMINSON, NEW JERSEY.

PLOW.

SPECIFICATION forming part of Letters Patent No. 227,606, dated May 18, 1880.

Application filed J nly 3, 1879 To all whom 'it may concern Be it known that I, SAMUEL L. ALLEN, of (Jinnaminson, Burlington county, New Jersey, have invented a new and useful Improvement in Plows, of which the following is a specification.

The main object of my invention is to so construct the mold-board, land-side, or jointer.

of a plow as to lessen the friction on the same and facilitate the proper turning of the furrow-slice, further objects being to regulate the draft of the plow and to construct a clevis which can be readily raised or lowered or moved from side to side without the necessity of removing and replacing a pin or b olt.- These objects I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawings, in which- Figure 1, Sheet 1, is a perspective view of the plow; Fig. 2, a sectional plan view on the line 1 2, Fig. 1; Fig. 3, a sectional plan' on the line 3 4, Fig. 1; Fig. 4, Sheet 2, aland-side view of the plow; Fig. 5, a transverse section on the line 5 6, Fig. 4; Fig. 6, a vertical section of the clevis, and Fig. 7 a sectional plan of the same.

A is the standard of the plow B, the beam D, the mold-board; E,'the land-side, and F the jointer; H, the share, and I the point.

The mold-board is made in the form of a series of arms, a, each of which is curved in precisely the same manner as the corresponding part of a solid mold-board would be, as

'- shown in Figs. 1, 2, and 3, the center lines of mold-board, and that the furrow-slice is turned over clean and without disintegration, even in light and sandy soils.

In order to accomplish this there must be no interference with the free passage of the furrow-slice over the mold-board, and the slots between the arms a are therefore unobstructed from end to end, the bridge-pieces by which the arms a, are connected together being made concave, as shown in Figs. 1 and 4.

The land-side E and jointer F are also slotted for the purpose aboi e set forth, and from the rearmost bridge, b, on the mold-board to a concave bridge, d, near the rear end of the slotted land-side extends a bracing-rod, c.

G G are the handles of the plow, the front ends of which are bolted to the standard, as usual, and stiffened by braces], extendingrearwardly from the standard and bolted both to said standard and to the handles. In or- .dinary plows these braces are liable to be strained or broken when undue lateral pressure is exerted upon the handles, a result which I obviate by providing each of the braces with an internal lug, i, the lugs abutting against each other and preventing the braces from being forced inward.

A socket, m, is formed between the standard and the lugs t, as shown in Fig. 3, this socket providing a convenient receptacle for the stem of a wrench or other tool, the use of which in the field is likely to be demanded.

The beam B is secured to the standard A by two bolts, n and s, the former passing verticall y through the beam and through a lateral slot, 19, in the fianged'top of the standard, and

the bolt s passing transversely through the rear end of the beam and through a vertical slot, q, in a projection, h, on the standard. By this means provision is afforded for throwing the front end of the beam up or down or to one side or the other, so that the plow-point can be thrown up or down or in or out, as desired.

To the front end of the beam B is bolted a plate, t, Figs. 6 and 7, having a flange, u, so shaped as to form on each side of the plate recesses 22, to which are adapted lugs o formed on a block, J, the latter having an inclined recess, 20, so that when the block is raised to the position shown by dotted lines in Fi 6 the lugs '0 will be free from the recesses v, and the block can be lifted or depressed, so as to adapt the lugs to another set of notches or remove the block from the plate.

It should be understood that thelugs o and recesses '0 are such that the lugs are not likely to be removed from the recesses by any movement which can be imparted to the block J by the team, the said block having to be lifted by hand in order to disengage the lugs from the recesses.

It will be noticed that the bearing of the block J on the outer face of the plate 1. is considerably below the lugs '0, so as to provide for an extended movement of the block before the lugs 'v are free from the recesses o, the latter being much deeper than usual.

The block J has a recessed flange similar to that of the plate at, and to the recesses of this flange are adapted lugs on a link, y, with which engages a second link, a", thicker at one end than at the other. so that when the thick portion of the link intervenes between the link y and the edge of the block J, as shown in Fig. 6, the lugs of said link 3 are retained within the recesses of the block; but when the link a: is turned so that its thin portion occupies the space between the link y and block J the said linkycau be moved inward until its lugs are clear of the recesses in the block, and the link can then be adjusted sidewise or be removed from said block.

I am aware that plows have been made in which the mold-board consists of a series of arms, an instance of such a plow being shown in Finlaysons English Patent No. 4,888 of 1824 but in this plow and in other plows of its class the arms are either straight or slightly bent, and are generally connected to each other at the rear ends, Whereas in my improved plow it is essential that the arms shall have the same shape as the corresponding parts of a solid mold-board, in order to turn the furrow, while the slots between the arms must be of a certain shape, as above set forth, and unobstrncted from end to end, so as not to interfere with the free passage of the furrow-slice. In these respects, also, my improved plow differs from plows with perforated mold-boards, and from potato-diggers in which curved arms are secured to the plowshare, the latter arms being purposely made of a different shape from that of a mold-board, in order to thoroughly break up and disintegrate the furrow turned up by the share.

I am also aware that it is not new to construct a skeleton mold-board of strips or plates secured to and projecting from a plowshare, slotted to form fingers of which the strips are continuations. Mold-boards have also been made of rods or bars secured directly to the rear edge of the share, and in some cases a solid mold-board has been slotted and bars arranged to work in the slots, so as to free the surface of the mold-board from accumulations of soil, the various bars in such case being connected by means of concave supports. It should be understood, therefore, that I do not desire to claim any of these features, my invention being restricted to certain improvements in the construction of plows of the same class to which those above cited belong; hence I claim as my invention- 1. A mold-board for plows, consisting of a series of arms, a, cast or formed integral with each other, and having the same shape as the corresponding parts of a solid mold-board, the slots between the arms following the course of the furrow-slice and being unobstructed from end to end, and the center lines of all the arms being parallel or concentric with each 7 5 other, all substantially as set forth.

2. The within-described mold-board or landside of a plow, the same consisting of arms a, integral with each other, and connected by concave bridge-pieces 1), whereby the slots between the arms are unobstructed from end to end of the land-side or mold-board, all substantially as specified.

3. The combination of the beam 13, the flanged standard A, having a slot, 19, the projection h, having a slot, q, the vertical bolt 12., passing through the beam and standard, and the transverse bolt 8, passing through the beam and through the projection h, as set forth.

4. The combination of the recessed plate t, the block J having a yoke or lugs and recesses, as described, the link 1 having lugs adapted to recesses on the block, and the link as, wider at one part than another, as set forth.

In testimony whereof I have signed my name 5 to this specification in the presence of two subscribing witnesses.
